如何在Yii中将变量从一个模型传递到另一个模型？

Question

I have this code which is inside a view Inventory.php from a model named Inventory. This is used to display the current ID being viewed:

<?php $inventoryID = $model->inventory_id; ?> <--- this one.

<h3>View Info for Inventory No. <?php echo $inventoryID; ?>: <?php echo $model->brand->brand; ?> <?php echo $model->model;?></h3>

I want to use it in another model named InventoryHistory because it will be saved in the InventoryHistory database. How do I do that?

Answer 1

Assuming inventoryID is the PK of InventoryHistory,

$inventoryID = $model->inventory_id;
$history = InventoryHistory::model()->findByPk($inventoryID);
